摘　　要：以主焦煤业2308工作面为对象,进行厚煤层综放工作面自然发火治理实践研究,在2308工作面煤自燃特性参数测试与分析基础上,选用采空区堵漏风+喷洒阻化液+注氮气技术措施综合治理方案。结果表明:2308面开采期间CO浓度未出现异常变化,未出现自燃升温迹象,消除了浮煤自然发火隐患,自然发火防治效果良好。Taking the 2308 working face of the main coking coal industry as the object,practical research was conducted on the control of natural combustion in thick coal seam fully mechanized top coal caving working face.Based on the testing and analysis of coal spontaneous combustion characteristics parameters in the 2308 working face,a comprehensive control plan was selected using the goaf leakage blocking air,spraying inhibitor liquid,and injecting nitrogen gas technology measures.The results showed that there was no abnormal change in CO concentration during the mining period of 2308 coal faces,and there were no signs of spontaneous combustion and heating up.The hidden danger of spontaneous combustion of floating coal was eliminated,and the prevention and control effect of spontaneous combustion was good.
